Americans 65+ with Alzheimer's, by sex (2026)
Almost two-thirds are women. At age 45, a woman's lifetime risk is about 1 in 5, and a man's is about 1 in 10. The main reason is that women live longer, and age is the biggest risk factor.

02 / Race and ethnicity
Not everyone has the same risk
Older Black Americans are about 2 times as likely to have Alzheimer's or another dementia as older White Americans. Older Hispanic Americans are about 1.5 times as likely.
Researchers say the difference is not caused by genes. It's linked to health conditions like high blood pressure and diabetes, and to life circumstances like income and access to care.
03 / Deaths
Fatality and death rate
Alzheimer's is ultimately fatal, and there is no cure. Worldwide, 57 million people had dementia in 2021, and Alzheimer's may cause 60-70% of those cases (WHO). About 12-13 million Americans care for someone with dementia without pay. In 2025 they gave 19.6 billion hours of care.

04 / Early onset
Not only the elderly
About 200,000 Americans have "younger-onset" Alzheimer's, which starts before age 65. The rare inherited forms caused by the APP, PSEN1 and PSEN2 genes can start in a person's 40s.
